The company was originally founded in New York City by the Berolzheimer family, and in 1969 became part of Berol Corporation. That same year Eagle Pencil Co. merged with Berol, so you will see many co-branded pencils (such as the Black Warrior or Electronic Scorer) starting in the 1970s.

In 1986 Berol was purchased by Empire, which was purchased by Sanford in 1995, which in 1992 became a division of Newell Rubbermaid (today known as Newell Brands).
